There seem to be alot of people interested in using sound waves to shift your natural brain freqency toward more sleeplike / creative / trippy states. There are also some companies out there trying to sell you programs that will do this. The this blows my mind because you can quickly learn that the entire concept that they work on is explained in one simple wikipedia page (http://en.wikipedia.org/wiki/Binaural_beats). And its a fairly simple process to make an audio file that has this effect for free.

Ive attached a few files that are designed to do just this. There is a frequency playing in each channel at exactly what rate the filename says. If you read the wiki page you should understand how to use these.
